it is covered with flat-topped cymes, which are five- 

 rayed, and these are succeeded by black berries. 



Viburnum lentago. (Sheepberry. Nanny-berry. 

 No. 40.) If you follow the Drive northerly, you will 

 find, on your right, a good-sized rock mass, about half 

 way between the first and second branching of the 

 Drive. The rock is about in line with East One Hun- 

 dredth Street. In the very shoulder of this rock, close 

 by the Drive, is this good specimen of nanny-berry. 

 It is a small-sized tree — about the proportions of the 

 black haw, with broadly ovate leaves that come down 

 to a long point. The leaves are simple, and opposite 

 to each other on the branch — as are the leaves of all 

 the Viburnums. Notice also the long leaf-stems, which 

 are wavy-margined and grooved. In the fall you will 

 see the tree hung full of fruit, clusters of oval ber- 

 ries, each about half an inch long, blue-black in color, 

 covered with a bloom. They are sweet and edible. 

 The berry stone is flat, oval, thin, and marked faintly 

 by groovings that run lengthwise across its flat sides. 

 The tree flowers in May or June, with the white, flat- 

 topped cymes characteristic of the Viburnums. 



While you are in this vicinity you should have a look 

 at the butternut tree, which is not far away. Follow 

 the east border of the Drive northerly until you come 

 to another rock mass. Just east of this rock you will 

 find the tree. It is, if I remember rightly, about the 

 best specimen of butternut in the Park. For some 

 reason, none of them is doing very well. The speci- 

 men here is rather a low tree, with the light gray bark 

 that is characteristic of the butternut. Its leaves are
